A drilling direction positioning device and its application method

Abstract

The invention discloses a drilling direction positioning device and an application method thereof. The drilling direction positioning device comprise a bass, a foundation seat, and a positioning rod; a circular dial is installed on the upper end surface of the base; scales are formed in the circumferential surface of the circular dial; the foundation seat is movably connected with the upper end surface of the circular dial through a vertical rotation shaft; the foundation seat is of hemisphere shape; a semicircular slot is formed along the radius plane where the central axis of the foundation seat is located; the positioning rod is arranged in the semicircular slot in a flexible connection mode through a horizontal rotation shaft; scales are formed along the outer circumferential surface of the semicircular slot; a position limiting component I is installed on the base to limit the movement of the base; a position limiting component II is installed on the foundation seat to limit the movement of the position rod; and a fixing part used for fixing arrangement is installed on the lower end surface of the base. Compared with the prior art, the drilling direction positioning device has the beneficial effects that errors of azimuth angles can be corrected and changed at any time; operation errors and system errors of the drilling direction positioning can be removed to some extent; and the accuracy of drilling results is enhanced.

Description

technical field [0001] The invention belongs to the field of tunnel engineering and machinery, and relates to a drilling direction positioning device and a using method thereof. Background technique [0002] At present, in the process of tunnel monitoring or blasting construction drilling, in order to ensure the accuracy of drilling results and actual drilling needs, it is necessary to accurately determine the azimuth angle of each drilling hole. At the same time, during the drilling process of drilling equipment, some lightweight drilling rigs are easy to deviate from the original direction with the vibration of the drill bit, making the drilling not straight, resulting in engineering losses such as drilling failure or drill pipe sticking or even drill pipe breakage. [0003] The traditional method is to use the azimuth dial of the theodolite to determine (or use the method of tape measure to roughly calibrate), each time the azimuth calibration technicians cooperate with t...

[0005] At present, the Chinese patent application publication number is CN103089244A for a laser locator. The locating instrument is composed of an angle ruler, a pointer, a sliding seat and a laser instrument. Placed on the body of the drilling rig, there are requirements for the drilling rig. During the adjustment process of the drill bit, it is easy to cause deviations from the previously determined azimuth.
